I did this 4 page worksheet as whole class at first then, as group work for the last two pages. You could do as test or a math station as well. The product is about dilations and volume.
1.The graph shows Triangle PQR with vertices P(2,4), Q(8,6), and R(6,2) and SU with endpoints S(5, 10) and U(15,5) At what coordinates would vertex T be placed to create Triangle STU, a triangle similar to triangle PQR
7. A circle with a radius of 3 units has its center at (-4,-2) on a coordinate grid. If the circle is translated 6 units to the right and 3 units up, what will be the coordinates of the new center?
8.Which statement is true when transforming XYZ to X’Y’Z’?
a. all the corresponding angles will increase by a multiple of 3
b. all the corresponding angles will increase by a scale factor of 1/3
c. all the corresponding sides are proportional, with a scale factor of 3
d. all the corresponding sides are proportional, with a scale factor of 1/3
